Now 16 days later when I asked what to do? It is not possible to actually know the best choise, but it is possible to get a good feeling.

The 7.0 was not an option and the poll also confirms that! I am a bit surprised the RSR E1 6.7 should stay. The RS Slalom MK3 6.2 has a good second place, intresting!

On the USM (ultimate speed meeting) I used the Neilpryde RS:Racing Evo1 6.2 (fast sail), I really like this sail. The RS:Slalom 5.5 amazes me every time I use it! With some TOW both sails have almost a guaranty for high speed no mather what.

Yesterday I rigged the 6.2 in very low-wind conditions, just to see if it is possible to get some TOW. I was really suprised the 6.2 was good enough to ride 90% of the time. According to windmeasurements the average wind was 12kn and the best gusts 17kn. With these very short gusts I wasn't very fast, but it proved comfy enough. So I decided to sell my 6.7 RS:Racing evo1.

I have to choose between 2 different but both fast sails. In terms of money both sails would cost about the same with 1 year use. I tried to sort out what is the difference??? IS there any difference, yes they don't look the same. I came up with this conclusion:

• RS:Racing Evo1 6.2, superstiff yet controllable in extreme conditions. In gusts it feels a bit to stiff for my 80kg weight, or my strenght is just not there when it should be. Highest acceleration if you can handle it.
  
• RS:Racing Evo2 6.2, softer than his older brother (evo1). Very controllable, I can't sail with negative outhaul. In gusts way better to hold the stance/close the gap/etc. when needed. WIth some outhaul tension the acceleration is good but the potential is a bit lower compared to the evo1.
  
• RS:Slalom MKIII 6.2, yes another size. I can sail with negative outhaul when needed, the easiest to hold stance. Theoretically the lowest acceleration...
  

Yesterday I ordered the sail, which I think is the winner for me:

Neilpryde RS:Slalom MKIII 6.2

I have had really some intresting points of view from other good speedsurfers, to call some names: Peter de Wit, Serge Beumer (vandenberg surf), Nico Nouwen, Martin van Meurs, Jacques vd Hout, Chris Lockwood and more.

Thanks this helped me a lot!!!
